Distributed Energy Resource Growth Scenarios and Distribution Load Forecasting
This Working Group is part of the Distribution Resources Plan (DRP) proceeding’s (R.14-08-013) Track 3 (Policy) Sub-track 1 (DER Adoption and Distribution Load Forecasting) activities, and is being organized pursuant to the Assigned Commissioner’s Ruling (ACR) issued February 27 in this proceeding. The purpose of this Working Group is to provide an opportunity for interested stakeholders and IOUs to discuss approaches to load and DER forecasting for distribution planning.
The Working Group met from April 17-May 24, 2017, and from April 18- June 13, 2018 to vet the following topics:
- System-wide DER growth assumptions
- Load forecasting at the distribution level
- Methodologies for the disaggregation of system-level DER forecasts to circuits
Final Reports are posted here:
2017: Revised Distributed Energy Resource Assumptions & Framework
2018: Distribution Forecasting Working Group Final Report
